Tools like that work up to a point. How well they work will depend greatly on the Mathematica code you've written. If that code makes extensive use of built-in functions such as say DSolve or NDSolve, these tools won't be very useful too you. Simply put, you cannot expect any of these tools to output C++ code for specialized Mathematica functions. >If it's relevant, my project calculates the Lyapunov exponents of >partial differential equations, and the goal is to find the simplest >chaotic PDE. It isn't the overall application that matters. It is the specifics of what functions you use that matter. >I'm considering trying Intel's Compiler 10.1 for MacOSX, but I am >very reluctant to abandon Mathematica to learn to use Intel's >interface and others' PDE solvers in C++. Understandable since this would not be a trivial undertaking especially if you have to re-implement something equivalent to Mathematica's NDSolve or some other specialized function.
